What is the trunk of the body?
The trunk of the body is the main, central part. It is everything except your head, neck, arms, and legs. You can think of it as the core.
The trunk is made of a few big areas. You have the chest, which is also called the thorax. Below that is the abdomen, which is your belly area. It also includes your entire back and the pelvis at the bottom. The trunk's main job is to hold and protect your most important organs. Your heart, lungs, stomach, and liver are all safe inside. It is the part of your body that connects all the other parts together. I hope this explanation is clear for you.
The trunk of the human body refers to the central part excluding the head, neck, and limbs. It includes the chest, abdomen, pelvis, and back. Essentially, it is the body’s core structure that connects all other parts.
In anatomy, the trunk houses vital organs such as the heart, lungs, stomach, intestines, liver, and kidneys. It provides protection and support for these organs through the rib cage and spinal column.
From a fitness perspective, strengthening the trunk (often called the “core”) improves balance, reduces injury risk, and enhances athletic performance. Exercises like planks, crunches, and squats target trunk muscles.
In simpler terms, the trunk is the torso, the main part of the body from which the head, arms, and legs extend.
